UNITED; STATES i PATENT; OFFICE JERSEY, AND MICHAEL V. CREEDON, OF THEWESTERN UNION TELEGRAZPHCOM- raw, or mew YORK, N. Y., A CORPORATION orNEW YORK GUIDE FOR BELT colvvnynns Application filed November 4, 1929.Serial No. 404,772.

This invention relates to a belt conveyer and more particularly to anendless conveyer for the transportation of fiat articles such astelegrams and the like in avertical or upright position.

In the handling of telegrams at a central oflice it' is necessary, insome instances, to transport the telegram from one portion of the ofliceto another-p This is done expeditiousl by employing a system ofconveyers. One orm of such conveyers consists of an open topped V-shapedtrough conveyer so. arranged that the telegrams or other articles willbe held in a vertical orupright position so that the address, routingdata, etc., may be read without removing the paper from Such conveyersare ordinarily termed V-belt conveyors due to the cross sectional shapeof the trough and such a V-belt system is fully disclosed in inapplication of dHumy, Birkmeyer and Grlflith, Serial No. 350,751, filedMarch 13, 1929, and entitled Belt conveyors.

Briefly the form of conveyer disclosed in said application consists of abase plate, preferably aninverted channel having two sidewalls attachedthereto and extending vertically ,above the base a slight distance thenhor zontally .towards each other over the troug edge'of the base andthence upwardly and diver ently to form a substantial V shaped open atthe top and at the'bottom. A housing orrectangular channel'is thusformed by the base plate and theoverlying side plates through which theconveyer belt travels with the belt sliding on the base plate. Thereturn reach of the belt is guided on rollers or other means separatefrom the trough members and disposed therebelow.

The present invention is especially concerned with a conveyer of thisgeneral nature, one of the objects being to provide a simpleconstruction of the trough and the guides for both the operating andreturn lengths of the belt.

Other objects and advantages will herein- 2 after appear.

In accordance with our invention we con "struct the side lates in suchmanner that they form both the -shaped trough and the coma ;copend--plete belt housing, thus eliminating the necessity for a separate baseplate. They also may be of such shape as to form the guide and supportfor the return length of belt.

The construction of the conveyer will be fully understood by referenceto the accompanylng drawings in which:

Figure -1 is a perspective View, partly in section, of a conveyerembodying my invention; 1

Figure 2 is a vertical sectional view of the I conveyer shown in Figure1;

. portions 12, by means of bolts 13 or other suitable fastening Y means.Immediately above the web portion 12 the plates extend horizontallyoutward away from each other to form a base portion 14 upon whichthe'belt rests, then vertical upward at 15 and then horizontally inwardtowardseach other to form shelves-or ledges 16 overlying the belt. Tlieparts 14, 15 and 16 form a substantially rectangular housing or conduitthrougi which the belt 17 travels. From the inner edges of the ledges 16the side plates extend upwardly and divergently to form a substantiallyV-shaped'trough having an open bottom and an open top. Flanges 18 areprovided at the top of the divergent walls. Below the web portion 12 thetwo sideplates extend horizontally outward at 19, vertically down-wardat 20 form, together a second conduit 21, partially open at the bottomwhich serves and support for the return reach stated above, travelsthrough the rectangular enclosure at the bottom of the trough and slideson the portion 14, of each of the plates which form the bottom wall ofthe enclosure. The belt passes around end rollers22 and 23 andhorizontally inward to as a guide f of the belt. The upper reach of theconveyer belt, as

. right position as shown and the and the lower reach' or return lengthof the belt is supported in the conduit 21. The belt is driven inanysuitablemanner as through one of the rollers 22 and 23.

iSupporting posts o'r standards 24, which may be channel irons areemployed to support the conveyer. The plates and 11 are secured to the0st 24 through the top flanges 19 which rest t ereon'and by the verticalwall 1 I modification in which the .web portions 12 are spaced apart byspacing sleeves 27 disposed on the clamping bolts 13. This form as theadvantage that the area of contact of the belt through the guide ways isreduced thus reducing the friction therebetween.

This arrangement also reduces the weight/of the construction.

The construction shown in Figure 5 is similar to that shown in Fi ures 1and 2 except thatsharp angle ben s are eliminated thus permittin thematerial to be more easily shaped. In this modification the main and Ireturn belt conduits areof oval cross section.

lon

Itw'ill be noted that in each of the forms the trough or articleguideway and the obconduit or belt guideway are formed entirely by thetwo side plates and therefore, that the conveyer may be assembled, bymerely clamping thetwo plates together by the bolts 13.1 The lates 10and 11 may be composed of relative y light material and may be readilyrolled into the shape shown. A conveyer construction is thus providedwhich is light, simle and inexpensive and which may be uicky and easilyassembled and disassemb ed. a

It is obvious that numerous changes may be made in the details ofconstruction and in exact shape of the plates 10 and 11 without Ideparting from the invention and therefore we do not desire to belimited to the exact details shown and described except in accordancewith the appended claims.

'What we claim is I 1. A belt conveyer having a trough provided withside walls and an open bottom, a housing beneath said trough of greaterwidth than said trough, a conveyer belt travelling in said housing, saidtrough andhousing being formed entirely by. two opposed plates suitablyshaped and secured together.

2. A belt conveyer having a trough provided with side walls and an openbottom, a

housin beneath said troughof greater width; than said trough, a guidewayformed beneath said housing and an endless conveyer belt having anoperating reach travelling in said housing and a return reach travellininsaid guideway,sa1d trough, housing and guideway being formed entirelby two opposed plates suitably shaped an 's ecured together.

3. A belt conveyer comfirising two longitudinally extending plates avinvertical web portions secured together, sai plates being shaped abovesaid web portions to form a substantially oblong conduit having an 0ening at the top of less width than said con uit,

said plates being further shaped to formv a substantially trough shapedguideway above said housing and a conveyer belt travelling in saidconduit, adapted to carry articles throu h said trough.

4. E belt conveyer comprising two longitudinally extending plates havinvertical web portions secured together, sai plates being shaped abovesaidweb portions to form a substantially oblong conduit having anopening at the top of less widths than said housing, said lates beingfurther shaped to form a troug 1 extending upwardly from said openin andbeing still further deformed below said web to form a'second oblongshaped guideway and a conveyer belt havin an operating reach travellingin said con Hit and a return reach travelling in said guideway.

5. A belt conveyer comprising two longitudinally extending plates havingvertical web portions secured together, spacing members between said webportions for maintainin the same in s acedparallel relation,

said p ates being de ormed above said web portions to form a pair ofopposed substantially horizontal be t uiding and supporting channelshaving orizontal lower and upper walls and a vertical sidewall and saidplates extending upwardly and divergently rom the inner edge of theupper walls of the channels to form a substantially V-shaped trough.

6. A. belt tudinally extending plates having vertical conveyercomprising two longiweb portions secured together, said plates beingdeformed above said web portions to form two opposed substantiallyhorizontal belt guiding and supporting channels having outwardlyextending horizontal bottom walls,

vertical sidewalls and inwardly extendin extending horizontal'bottomwallswertical 'a' trough there above, sa1d plates also being deformedbelow said web portions to produce a horizontal support for the returnlength of said belt.

In testimony whereof we afiig our signatm'es. a/ a FERNARI) E. DHUMY.
